基于VTK三维地震数据体绘制系统框架

针对地震数据信息量大的特点，文中提出了一种针对三维地震数据体绘制系统的框架。解决的方法是将数据处理、用户交互、渲染绘制分离成三个模块，并且设计了层次结构来保持模块之间的独立性，便于各个模块的修改、更换和扩展，提高了可视化绘制系统快速开发的灵活性。基于三维可视化开发工具包VTK,设计并编程实现了一个地震数据体绘制系统界面。通过实验结果证明，此体绘制方案是可行的、有效的。

Framework of Volume Rendering System for 3D Seismic Data Based on VTK

Aiming at the large amount of seismic data, a framework for the rendering system of three dimensional seismic data is pro posed. The framework divided the system＇s major function into three modules including data process module, user interface （UI） module and rendering module. At the same time the framework generates three layers which can keep the independence among the modules. The framework also makes the system more flexible, extensible and adaptable. Based on VTK, design and program the rendering system of three dimensional seismic data. Experimental results show that the methods discussed in this paper are effective and correct.
